> We found some jobs were stuck in KILL_WAIT for days on end. The RM shows them
> as RUNNING. When you go to the AM, it shows it in the KILL_WAIT state, and a
> few maps running. All these maps were scheduled on nodes which are now in the
> RM's Lost nodes list. The running maps are in the FAIL_CONTAINER_CLEANUP state
